I guess searching for Allana Potash or AAA along with my other terms buried this link. Thanks!

So 6 years (assuming this is an underdeveloped region, which seems like a given) as long as half of the product is exported. Given present African demand, that shouldn't be a problem, but this is potentially out of Allana's control since ICL will be the one marketing the product. Of course ICL will own almost 40% of Allana by that point, so they have vested interests here too... I guess we'll have to see if Ethiopian internal demand rises above 500,000 tpy by the time Allana ramps up production.
